Sympathetic ganglion?
Answer:
Sympathetic ganglion can be divided into two major groups, paravertebral and prevertebral (or preaortic), on the foundation of their location within the body. Paravertebral ganglion generally pull the wool over your eyes on each side of the vertebrae and are connected to form the sympathetic manacle or trunk. There are usually 21 or 22 pairs of these ganglia: 3 contained by the cervical region, 10 to 11 in the thoracic region, 4 within the lumbar region, 4 in the sacral region, and a single, unpaired ganglion lying surrounded by front of the coccyx called the ganglion impar.
Sympathetic ganglion are the ganglia of the sympathetic disconcerted system. They deliver information to the body about stress and impending difficulty, and are responsible for the familiar fight-or-flight response. They contain approximately 20000–30000 bottle cell bodies and are located close to and either side of the spinal cord surrounded by long chains.

Anatomy
Sympathetic chain ganglion
The bilaterally symmetric sympathetic chain ganglion, also called the paravertebral ganglion, are located just anterior and lateral to the spinal cord. The secure extends from the upper neck down to the coccyx, forming the unpaired coccygeal ganglion. Preganglionic nerves from the spinal cord synapse at one of the secure ganglia and the postganglionic fiber extends to an effector, typically a visceral organ within the thoracic cavity.
Collateral ganglia
Neurons of the collateral ganglion, also called the prevertebral ganglion, receive input from the splanchnic nerves and innervate organs of the abdominal and pelvic region. These include the celiac ganglia, superior mesenteric ganglion, and inferior mesenteric ganglia.
21 or 22 pairs of these ganglion: 3 in the cervical region, 10 to 11 within the thoracic region, 4 in the lumbar region, 4 contained by the sacral region, and a single, unpaired ganglion lying in front of the coccyx call the ganglion impar.
